When the penguins came into their planet for the first time when they were four, they both happily accepted them completely. Sharon designed outfits to newest types of fashion while Sweeney pursued his new goal to become a filmmaker to make his documentary and action adventure movies about life on Mobius and Earth. Regardlessly, Sonic and Sweeney have an extreme closer father-son relationship just like he and Emily as his co-successors as the next heroes of Mobius when both siblings inherited their father’s speed powers.
